READMISSION RISK POOL · ANALYTICAL PLATFORM
Understand how remaining readmission risk changes after discharge.
Readmission Risk Pool (RRP) connects an organization’s data and risk provider to repeated, point-in-time assessments. The readmit R package supplies the shared analytical workflow, retained history, and a project-owned application.

THE ANALYTICAL QUESTION
One prediction at discharge cannot describe a changing risk pool.
As follow-up time passes and new information becomes available, the set of eligible discharge episodes can change. A later assessment asks about the remaining probability of a first hospital readmission strictly after that time and through 30 elapsed days after the original discharge. Each assessment keeps the original endpoint; it does not restart the 30-day window.
RRP applies shared eligibility rules to the episodes an organization supplies, records accepted estimates and other dispositions at each chosen time, and derives current-risk, trajectory, and operational-summary products. Its trajectories are recorded assessments, not continuous predictions between runs.
WHAT THE PLATFORM ENABLES
From local inputs to an inspectable risk pool.
The organization controls clinical sources, mapping, the risk provider, and how results are evaluated and used. readmit provides the shared structure around those choices.
Reassess at chosen times
Apply discharge-anchored eligibility and point-in-time event availability before requesting risk for eligible episodes.
Keep the full history
Retain completed runs, including accepted estimates, provider failures, and ineligible episodes, so earlier results remain inspectable.
See the pool and its trajectories
Refresh CSV products from history and explore current remaining risk, recorded episode trajectories, and operational scope in the project app.
THE PROJECT-OWNED APPLICATION
A working view of the current pool and recorded risk.
The existing application lists eligible discharge episodes and their current estimates. Selecting an episode reveals its accepted assessments across runs.
